This journal article discusses incorporation of the Winogradsky Column into high school science classrooms to demonstrate nutrient cycles and inter-relatedness of organisms in the environment.

Students learn about inheritance, evolution, and ecosystems. Some topics explored in the tutorial are five kingdoms, respiration, energy transfer, and nutrient cycle.

Everything on our planet is linked by a giant recycling system called the biogeochemical cycle. How our planet recycles and reuses everything we need to support life is explained by making a miniature biosphere in this lab. You will also...

Kids learn about the oxygen cycle and how this nutrient travels through the ecosystem to sustain life on Earth.

Kids learn about the carbon cycle and how this nutrient travels through the ecosystem to sustain life on Earth.

Kids learn about the nitrogen cycle and how this nutrient travels through the ecosystem to sustain life on Earth.

An explanation of ocean chemistry, supported by illustrations, for example, of the global carbon cycle in the 1980s and the annual carbon dioxide flux. The concentration of nutrients in the ocean is discussed for its impact on marine...

Through a series of multi-media learning activities, students will assess the dependence of all organisms on one another and the flow of energy and matter within their ecosystems.

[Free Registration/Login may be required to access all resource tools.] In this module, students will learn about the cycles of nature (water, carbon, nitrogen, and phosphorus) that support the flow of nutrient matter through an...

Students learn about energy flow in food webs, including the roles of the sun, producers, consumers and decomposers in the energy cycle. They model a food web and create diagrams of food webs using their own drawings and/or images from...

Slideshow that looks at energy flow in an ecosystem. Explains what an ecosystem is, how energy flows through it, the producers and consumers of energy, and food chains. Links to a video about plastic debris in the ocean.

This lesson will provide the characteristics of the domain fungi.

Ecosystems contain two kinds of commodities: matter (nutrients) and energy. Nutrients cycle through the ecosystem, available for repeated use by organisms. These cycles of use and reuse are called biogeochemical cycles. Energy instead is...

Students explore the biosphere's environments and ecosystems, learning along the way about the plants, animals, resources and natural cycles of our planet. Over the course of lessons 2-6, students use their growing understanding of...
